Be it known that I, RALPH M. BARNETT, a citizen of the United States,residing at Lenoir City, in the county of London and State of Tennessee,have invented certain new and useful Improvements in Grates, of whichthe following is a specification, refere'nce being had to theaccompanying drawings.

ments in grates and has relation more particularly to a device of thisgeneral character especially designed and. adapted for use in connectionwith household'ranges or the like and it is an object of the inventionto provide a device of this character having novel and improved meanswhereby water may circulate directly under the fire thus eliminating theuse of water backs and coils.

Furthermore it is an object of my invention to provide a novel andimproved fitting The novel features of the invention will be carefullydefined in the appended claims.

In order that my invention may be the 7 better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein-'- Figure 1 is a view partly in plan and partly insection of the device as herein embodied; and Fig. 2 is a sectional viewtaken substantially on the line 2-2 of Fig. 1.

As disclosed in the accompanying drawings S denotes a fragment of arange of conventional construction and with which my improved grate Gcoacts. As herein dis-,

closed the grate G is of such configuration as to properly fit withinthe fire box of the stove and is provided at one extremity with atrunnion 1 terminating in the angular portion 2 whereby the same may beoperatively engaged with a suitable implement for imparting requisiterocking movement to the grate. The opposite extremity of the Thisinvention relates to certain improvegrateiG is provided with thetrunnion 3,

of a materially v greater diameter than the d ameter of the trunnion 1and saidtrunnion 1s provided'with' the ports 4i in com mu'nicationwiththe ports disposed longi,- tudinally thereof and 111 communication withthe opposite extremities of the conduit 5 formed within the grate 1 anddisposed around the margins thereof.

The trunnion 3 projects exteriorly of the stove S and is mounted withinthe sleeve or fitting 6 provided with the diametrically opposed ports 7and 8 adapted to'communi cate with the ports 4 hereinbefore referred toand said port '7 being adapted for communication with a suitable sourceof water supply while the port 8 is adapted for communication with aconventional boiler or other point of delivery. I

The trunnion '3 snugly fits within the sleeve or fitting 6 and has itsfree end portion reduced to afford an annular shoulder 9 adapted tocoact with the annular shoulder 10 within the bore of the sleeve orfitting 6 afforded by restricting the intermediate diameter of the boreof said sleeve or fitting and between said shoulders 9 and 10 is adaptedto be positioned suitable packing. Insertible within the outer extremityof the sleeve or fitting 6 and coacting with the outer annular shoulder11 afforded by'the restricted portion of the bore of said sleeve orfitting is a conventional gland nut 12 whereby additional packing may beemploved in connection with the trunnion 3.

From the foregoing description, it is thought to be obvious that a grateconstructed in accordance with my invention is of an extremely simpleand comparatively inexpensive nature and is particularly well PatentedFeb. 15 1916.

adapted for use by reason of the convenience 1 and facility with whichit may be assembled, and it will also'be obvious that my invention issusceptible of some change and modification without material departurefrom the principles and spirit thereof and for this reason I do not wishto be understood as limiting myself to the precise arrangement andformation of the several parts herein shown in carrying out my inventionin practice.

' hat I claim is 1. A fire grate having a conduit therein extendingsubstantially entirely around the marginal portion thereof, said gratebeing communication with the extremities of the V conduit. 7

2. A fire grate having a conduit therein extending substantiallyentirely around the marginal portion thereof, said grate being providedwith an extension having ports in communication with the extremities ofthe conduit, said extension serving as a trunnion, a sleeve surroundingsaid extension and proiide'd with ports adapted to communicate with theports of the. extension.

3. A; fire grate having a conduit therein extending substantiallyentirely around the marginal portion thereof, said grate being providedwith an extension having ports in communication With the extremities ofthe conduit, said extension serving as a trunnion, a sleeve surroundingsaid extension and provided With ports adapted to communicate With theports of the extension, the outer extremity of the extension beingreduced to afford an annular shoulder and the intermediate portion ofthe bore of the sleeve being restricted to afford an annularshoulder,and packing interposed between said annular shoulders.

4. A fire grate having a conduit therein extending substantiallyventirely around the marginal portion thereoflsaid grate being providedwith an extension having ports in communication with the extremitles ofthe conduit, said extension serving as a trunnion, a sleeve surroundingsaid extensionand pro ided with ports adaptedto C0111- nnilnieate' withthe ports of the extension, said extension having its outer extremityiofreduced diameter to afford an annular shoulder, the intermediate portionof the bore of the sleeve being restricted to =af-I In testimony whereofI hereunto afiix my signature in the. presence of two Witnesses.
